Description

RELATED APPLICATIONS

[0001] The present application is based on, and claims priority from, Taiwan Application Serial Number 94109442, filed Mar. 25, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND

[0002] 1. Field of Invention

[0003] The present invention relates to circuit boards. More particularly, the present invention relates to circuit boards capable of indicating the temperature of hot elements thereon.

[0004] 2. Description of Related Art

[0005] With the growth of processing speed and increase of functions, computers are now consuming more and more power, which makes the essential parts, i.e. the circuit boards, in the computers undertake more and more power conversion and generate more and more heat to be dissipated. If users want to examine the elements on the circuit board, they could likely get burned because they have no means for determining temperatures thereof. Consequently, in addition to the effort to further impro...
